To all whom it may concern:

Be it known that I, Josnrn F. J or, a citizen of the United States,residing at Franklin, in the county of Venango and State of 5Pennsylvania, have invented certain new and useful Improvements inConveyers, of which the following is a specification.

This invention relates to certain new anduseful improvements inconveyers of the well known chain and scraper type and is particularlydesigned for use in loading machines of the type disclosed in my UnitedStates Letters Patent No. 1,306,064, dated June 10, 1919, althoughcapable of general use.

An object of the invention is to improve the construction of the fli htsor scraper bars disclosed in my co-pen ing application for United StatesLetters Patent upon con- 9 veyers, filed Jan. 24, 1924, Ser. No,688,183,

whereby such scraper bars are made extremely strong and urable, althoughsimple and inexpensive to manufacture.

Otherobjectsmillappear as the nature of the invention is betterunderstood, and the same consists in the novel construction, combinationand arrangement of parts hereinafter more fully described, illustratedin the accompanying drawin and claimed.

characters indicate corresponding parts throughout the several views,

Fig. 1 is a fragmentary view, partly in plan and partly in section,illustrating a portion of a conveyer constructed in accordance with thepresent invention,

Fig. 2 is a front elevation of one of the scraper bars, detached,

Fig. 3 is an enlarged-end elevational view of the device shown in Fig.2,

Fig. 4 is an enlarged transverse section taken on line 44 of Fig. 2, and

Fig. 5. is a .view similar to Fig. 4 taken on line 5-5 of Fig.1.

Referrin more in detail to the several views, it Wlll be understood thatthe present improvement relates to the construction of the endlessconveyer member in the above mentioned patent and application comprisingbroadly the chains -35- connected by transverse scraper bars, as at-36-, the

chains --35 broadly comprisingpairs of mner links 37- and outer links'38 pivotall connected by pins -40 and spaced y rollers +41-.

,In accordance with the present invention, the scralper bars -36- are ofsubstantially mverte V-shape in cross section with -the front leg orflange.-F-- vertical and the othenflange F- longer and inclined, thelatter flange being gradually increased in width from the ends to thecenter of the scraper bar so as to be of outwardly curved form asindicated at C. This gives great strength for withstanding the severepressure of coal against the scraper bar when the conveyer is in use.

In order to further strengthen the sore er bar, and to enhance itsloadingor conveym efliclency, the flange -F'- is formed wit a pluralityof s aced ribs -R which merge with the said ange ad'acent its lower edas at M and gradua y increase in heig t as shown in Fi 4 to the pointwhere they terminate at t e juncture of the flanges -F and F'.

The chains are passed about sprocket wheels which "preferably have guiderollers at their inner sides, and in order to ermit passage of thescraper bars aroun these rollers, the ends of flange F are notched as at--N. 30 In the drawing, w erem like reference The ends of the scraperbars are formed with pairs of oppos1te extending ears 36'- adapted forfree slidable reception upon the inwardly extending studs or heads 4:2-provided on certain ones of the pivot pins 40.

From the foregoing description, it will be seen that the presentconveyer scra er bar embodies all of the advantages of tlEat disclosedin my above mentioned co-pending application, and at the same time ismore durable and efiicient in operation.

Minor changes may be made without departing from the spirit and scope ofthe invention as claimed. I

What I claim as new and desire to secure by Letters Patent is':-

. 1. In an endless chain and scraper eonveyer member, a scraper bar ofsubstantially inverted V-sha e in cross section having one flangeinclined and of gradually increased width from the ends to the centerthereof.

2. In an endless chain and scraper conve er member, a scraper bar ofsubstantially inverted Vesha e in cross section having one flangeincline and of gradually increased width from the ends to the and aplurali of spaced transverse .ribs formed on sai flange.

3. In an endless chain and'scraper conve or member a scraper bar ofsubstantia y inverted \i-sha in cross section having one flange inc inedand of gradually increased width from the ends to the center thereof,and a plurality of spaced transverse ribs formed on said flange, saidribs increasing in height toward and terminating at the point ofjuncture of the scraper bar flanges.

4. In an endless chain and scraper conveyer member, a scraper bar ofsubstantially inverted V- hape in cross section having one flangeinclined and of gradually increased width from the ends to the center 20thereof, pairs of opposed link pivot pins center thereof,

having inwardly extending studs, and ears formed upon the ends of saidscraper bar I freely telescoping onto said studs.

5. In an endless chain and scraper conveyer member, a scraper bar ofsubstantially inverted V-shape in cross section having one flangeinclined and of gradually increased width from the ends to the centerthereof, pairs of opposed link pivot pins having inwardlg extendingstuds, and ears formed upon t sends of said scraper bar freelytelescoping onto said studs, the remaining flan e of said scraper barbeing vertical and aving notches in the ends of its free edge. a

In testimony whereof I aflix my signature. I
